Vodacom's Tricks to generate interest.

My Dad have a contract with Vodacom and the account was in good standing until the company my Dad was working for, closed down and everyone was retrenched in February 2025. We contacted vodacom in March of 2025 and informed them of my Dad's employment status, and also requested a settlement amount to cancel the contract. We were told by Vodacom that they are unable to assist us as the account was Not in arrears. Strange right? So eventuality when the account went into arrears we called Vodacom again and they said we need to pay the arrears before cancelation can happen. We paid the arrears, and requested the settlement amount to cancel. Vodacom was not forthcoming with the settlement amount, instead they kept billing my Dad monthly, regardless of our request for a settlement amount. Naturally the account went into arrears again as by June 2025 my Dad reached his retirement age and also fell ill. Every time I tried to get the settlement amount from Vodacom, they kept giving us the run-around. Recently my Dad received an email from HP Attorney's requesting payment of the arrears. I emailed them back saying I want the full settlement amount so that I can pay-up this account. My Dad has since fallen ill and is now bed ridden and we as the kids decided to further handle and communicate with HP Attorney's. HP Attorneys also started to call my Dad every single day, to a point where I had to remove the sum card from the phone. To date, we have not received the settlement amount and we are being sent from pillar to post. Seemingly Vodacom is generating more interest by keeping contracts open. We don't understand why they can not provide us with a settlement amount so that we can close this account once and for all. Their customer service agents are not helpful. Cancelations department wants us to first pay the arrears before we can get a settlement amount. How does that even make sense?
